Benefits of technology

[0007]There is a need in the art for a fibre-reinforced composite containing a particulate filler to impart the desired filler properties, and a method of manufacture thereof, which can provide the composite with the required combination of properties, both from the filler and from the fibre and resin matrix components, in a cost-effective, efficient and reliable manner.
[0028]By distribution of the filler preferentially on the surface of the fibrous layer, this can allow higher filler concentrations to be used than would be feasible with traditional filled resin systems, in particular epoxy resin systems. The multi-laminate embodiments can provide easy control the regional placement of the filler particles within a laminate configuration to allow specific optimisation of the laminate performance.

Problems solved by technology

Although the fire-retardant performance increases with increasing concentration of fire-retardant fillers, however the thermal and mechanical properties are in general reduced with increasing filler concentration in a cured fibre-reinforced laminate.

example 1

[0062]Following laboratory-based formulation and development work, and preliminary fire tests, large scale laminates were manufactured embodying the present invention. In these laminates, the volume fraction Vf was 46.6% and the fibre diameter was 6 microns. The filler used in the example was a fire retardant sold by Albermarl Corporation under the trade mark Martinal, and under the product names OL-104 / LE, and the filler particle size was estimated to be approximately 3.3 microns.

[0063]The epoxy resin used was the resin sold by Gurit (UK) Limited under the trade name ST70FR including the fire-retardant filler particles identified above. These laminate samples were tested for thermal and mechanical performance (glass transition temperature and inter-lamina shear strength respectively), and the results compared to a control sample of ST70 which employed the same epoxy base resin system without fire-retardant filler. Panels were also tested in accordance to the fire test of British St...

Abstract

Prepeg for manufacturing a fibre-reinforced composite material, the prepreg comprising a layer of dry fibres and a layer of resin material adhered to a surface of the layer of dry fibres, the resin material having a plurality of particles dispersed therein, the particles have an average particle size that is larger than the average fibre separation of the layer of dry fibres.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a fibre-reinforced composite material, to a method of manufacturing a fibre-reinforced composite material and to a prepreg for manufacturing a fibre-reinforced composite material.BACKGROUND[0002]It is known to provide structural fibre-reinforced hot-melt epoxy composite materials. Inorganic fillers are commonly added to epoxy resin systems to modify properties, for example to modify the thermal and mechanical performance, to impart fire-retardant properties, to customise the rheological and handling properties, to increase ultraviolet (UV) radiation stability, and to provide weathering resistance. Traditionally, these fillers are dispersed homogeneously throughout the resin matrix. Many improvements in properties do not require such homogeneous dispersion and so this may result in a material which is thus either over-engineered for the application or, conversely, reduced in one or more other properties.[0003]EP-A-0124403 d...
